Clock case

5 Claims.

This invention relates to improvements in clock cases, and moreparticularly to the case-band and base construction of the case.

One object of the invention is to provide a 5 clock case capable oibeing simply manufactured and assembled at minimum cost.

With the above and other objects in view, this invention includes allimprovements over the prior art which are disclosed in this application.

In the accompanying drawing, in which one way of carrying out theinvention is shown for illustrative purposes:

Fig. 1 is a perspective view of a case-band and base assembled togetherin accordance with this invention;

Fig. 2 is a fragmental front elevation of the construction shown in Fig.l;

Fig. 3 is a fragmental sectional view on line 3-3 of Fig. 2;

20 Fig. '4 is a perspective view of the base prior to being assembled;and

Fig. 5 is a perspective view of the case-band prior to being assembled.

In the description and claims, the various parts are identied byspecific names for convenience, but they are intended to be as genericin their application as the prior art will permit.

Referring to the drawing, II) is a case-band rolled up to annular formfrom a strip of sheetmetal, and having the case-back I I secured theretoin a usual manner. In view of the fact that the case-band I is rolled upfrom a strip of sheet-metal, it has, in its finished form, a split orline of separation I2. On each side of the split I2, the case-band isprovided with a plurality of openings in the form of slots I3. The baseI4 is shaped up from sheet-metal and has its top-surface I5 thereofshaped curved, as shown, to suitably t the curvature of the casebandIII. The portion I5 of the base has struck up therefrom a plurality oftongues I6 which are spaced to correspond to the spacing of the slots I3in the case-band. Thus, the tongues are adapted to extend up through theslots I3 and be bent down, as shown in Fig. 3, to rmly secure thecase-band to the base.

By virtue of this improved mode of construction, a case-band can beformed rapidly and at low cost from a strip of sheet-metal, instead offorming the same from a more costly portion of an integral tube, andalso more economically than would be necessary in case the band were tobe formed with overlapping portions at the split I2 to form a seam.

This improved construction forms an eiiicient,

readily-assembled construction of minimum cost which, in the finishedform, as will be evident when the entire clock case with bezel, dial andmovement are assembled therein, will entire1y` conceal the split I2 andgive ampie strength to 5 the case-band without the need of joining thesplit ends of the case-band together other than is accomplished in theriveting action which secures them to the base.

'The invention may be carried out in other specific ways than thatherein set forth without departing from the spirit and essentialcharacteristics of the invention, and the present embodiment istherefore to be considered in all respects as illustrative and notrestrictive, and all changes coming within the meaning and equivalencyrange of the appended claims are intended to be embraced therein.

I claim:

1. A clock case including: a clock base forming one part; a splitcase-band forming another part and having a minor portion of itscircumference engaged against the base and with the split intermediatethe ends of the area of engagement of the case-band and base, the mainportion of the circumference of the case-band forming part of theoutside surface of the clock case; and means adjacent and at oppositesides of said split securing portions of the case-band on opposite sidesof said split, to the base.

2. A clock case including: a clock base forming one part; a splitcase-band forming another part and having a minor portion of itscircumference engaged against the base and with the split intermediatethe ends of the area of engagement of the case-band and base, the mainportion of the circumference of the case-band forming part of theoutside surface of the clock case; and means integral with one of saidparts and adjacentand at opposite sides of said split securing portionsof the case-band on opposite sides of said split, to the base.

3. A clock case including: a base forming one part; a split case-bandforming another part and engaged against the base and with the splitintermediate the ends of the area of engagement of the case-band andbase; one of said parts being provided with openings on opposite sidesof said split; and means struck up from the other of said parts andextending through said openings and securing portions of the case-bandon opposite sides of said split, to the base.
